As liquids approach the glass transition temperature, dynamical heterogeneity emerges as a crucial universal feature of their behavior. Dynamic facilitation, where local motion triggers further motion nearby, plays a major role in this phenomenon. Here we show that long-ranged, elastically mediated facilitation appears below the mode coupling temperature, adding to the short-range component present at all temperatures. Our results suggest deep connections between the supercooled liquid and…

Excess wings and asymmetric relaxation spectra in a facilitated trap model.
A minimal empirical model is constructed to describe this physics and introduce dynamic facilitation in the trap model, which was initially developed to capture the thermally activated dynamics of glassy systems.
A theory of localized excitations in supercooled liquids.
The role of structure and elasticity in driving glassy dynamics through the creation and relaxation of localized excitations is strengthened through the created and relaxed elastic bonds holding the local structure of an inherent state.

Aging in a mean field elastoplastic model of amorphous solids
We construct a mean-field elastoplastic description of the dynamics of amorphous solids under arbitrary time-dependent perturbations, building on the work of Lin and Wyart (2016) for steady shear.
Role of fluctuations in the yielding transition of two-dimensional glasses
We numerically study yielding in two-dimensional glasses which are generated with a very wide range of stabilities by swap Monte-Carlo simulations and then slowly deformed at zero temperature. We
Rejuvenation and shear banding in model amorphous solids.
It is argued that the transition between brittle and ductile yielding in amorphous materials occurs around a comparable parent temperature, as well as the contributions of pressure and density changes, which are negligible compared with the changes of softness caused by structural rejuvenation.
